What's happening? Despite numerous pledges to clean up the government, a report has found Rishi Sunak broke parliamentarian rules when No10 acknowledged the Standards Committee was investigating him.
After the numerous sleaze scandals of the Boris Johnson government and the chaos of Liz Truss's weeks in office, Sunak said he wanted to bring such drama to an end.
In his first speech outside Downing Street, he pledged "integrity, professionalism and accountability at every level".
But since then he has been forced to replace several ministers after they were found guilty of bullying or failing to declare their taxes properly.
On top of this, Sunak himself has been found guilty several times of breaking various laws and parliamentary rules.
Here Yahoo News UK breaks down the three times Sunak has got into trouble for breaking the rules while serving in government.
No. 10 confirms probe into wife's investments
On 14 September, the Commons Standards Committee found Sunak had broken the MPs' code of conduct when No. 10 confirmed details about an investigation into his wife Akshata Murty's financial interest in a childminding company.
The committee found that it was a "minor and inadvertent" rule breach.
MPs are forbidden from disclosing details of "any investigation by the Parliamentary Commissioner for Standards except when required by law to do so, or authorised by the Commissioner."
In this case, Downing Street provided a statement to the media that contained details of the probe.
Standards commissioner Daniel Greenberg said: "Whilst it was open to the media to speculate, when Mr Sunak's spokesman confirmed to the media that the inquiry related to Mr Sunak's 'links to a childcare firm in which his wife is an investor' he disclosed details about my inquiry."
The Standards Committee stopped short of recommending any sanction against the prime minister, given the nature of the rule breach.

Failure to wear a seatbelt
In January, Sunak was fined by Lancashire Constabulary after he was spotted not wearing a seatbelt in an Instagram video filmed to promote levelling-up funding.
The PM paid the fine and issued an apology saying he "regrets deeply" not fastening his belt.
Lancashire Constabulary did not reveal how much Sunak was fined, but fixed penalty notices for seatbelt offences are usually £100, rising to up to £500 if taken to court.
Labour criticised him for having a "lack of judgment".
Sunak became the second prime minister in history to be fined by the police, after his predecessor Johnson.
While still chancellor, Sunak and then-prime minister Johnson were fined in April 2022 for breaking COVID rules after it emerged several illegal gatherings were held at Downing Street.
The fine related to an event on "June 19 2020 at the Cabinet Room... between 1400 and 1500" and that he had been part of "a gathering of two or more people indoors", which was banned at the time.
At the time, Sunak said: "I understand that for figures in public office, the rules must be applied stringently in order to maintain public confidence. I respect the decision that has been made and have paid the fine."
After the fines, many people did not think the Johnson-Sunak government would survive much longer, but the embattled PM managed to stay in post until 9 June, 2022.
